To paint over grooved wood paneling, mask it, caulk the seams, apply latex primer, and paint the paneling with latex interior paint. The supplies you need for this two-day project are drop cloths, masking tape, a stepladder, latex caulk, an applicator, sandpaper, primer, latex paint, a paint roller and paintbrushes.
- Protect the work area
Apply masking tape around the edges, trim, baseboards and wall moulding. Cover the floor with drop cloths.
- Caulk the seams
Apply latex caulk to the paneling seams, and smooth the surface with a flat applicator. Let the caulk dry completely, and then sand it until the paneling looks and feels smooth.
- Apply latex primer
Prime the wall with latex primer. Prime the edges and corners with an angled paintbrush, and use a flat paintbrush to push the primer into the paneling grooves. Apply additional primer with a thick-nap paint roller. Let the primer dry according to the directions on the can. Rinse the brushes and roller.
- Paint the paneling
Apply a coat of latex interior paint with the same technique you used to prime the wall. Let the paint dry, and apply a second coat if desired. Remove the masking tape when the paint is dry.
